Détails:A Dornier 228-202 passenger plane, operated by Sita Air, was destroyed when it crashed shortly after takeoff from Kathmandu-Tribhuvan Airport (KTM), Nepal. All 19 on board were killed.The airplane took off from runway 20 at 06:17, bound for Lukla Airport (LUA) and subsequently stalled and crashed.

Probable Cause:

"No faults were found with either of the engines, there was no evidence of a bird ingestion into the engine. Both engines were producing low power at impact, both propellers were in their normal operating range. However, an insidious power reduction occurred starting at 70 KIAS which went unnoticed by the crew. Following lift off the pitch attitude was set too high for the aircraft to maintain V2, the aircraft's speed fell below V2 requiring more thrust than available to accelerate again. The investigation was unable to determine the cause of the thrust reduction."
